To all whom may camera: I' j Be it known that I, WiLLrAM W. Feinwe-WORTH, a citizen of the United States, re-

siding at Littleton, in the county'of Arapahoe and State ofv Colorado,have invented certainl new and useful Improvements in Renovators, ofwhich the following is a. specificatio This invention relates toimprovements in renovators, and one of the objects of the same is toprovide .an improved apparatus of this character, whereby a blast ofIair, may be employed for removing and picking up dirt and foreignparticles from the surface or article to be renovated.

Av further object is to provide improved means'whereby the dust ladenair may be cleaned yor purified of the dirt, and the clarified air againused as a blast against the surface to e'ectively and thoroughly cleanand renovate the same.

' accomplishment of other new and useful objects as will appear,l theinventiony consists in the features of novelty in substanf tially theconstruction,'combination and .ar-f i 'rangement of the several partshereinafter `more -fully described and claimed and shown F'inltheaccompanying drawings illustrating the invention and in which:

and partly in section of another form of thel invention.

' .Referring more particularly to the drawo ings, the numeral-110designates generally a cleaning" head.l which may be of any desired sizeand configuration. The cleaning head is hollowandis providedwith a'partition 11 dividing the same linto a cu-p-` shaped'receiving chamber12 and an air in- 5let chamber 13'. The' chamber 12 is of asubstantially cup shape formation, 'having an open bottom which latteris adapted to be placed against and'moved over the surface to berenovated.l rThe chamber 13 is provlded with any desired number ofoutlet openings 15,l extending through the bottom `thereof preferably inclose proximity to the bottom'of the chamber 12, and form communicationbetween the two. chambers so that vwhen the cleaning head is placedagalnst and moved over the surface or article to be renovated and closedthereby, the penings 15 will also be moved over the surace.

rlhe chamber 13 is provided with an inlet 16 and the chamber 12 isprovided with an outlet 17. A fan 18 is suitably mounted and'is operatedby a suitable motor 19. The fan casing forms part of the cleaning headand hascommunication with the chamber 12, so that', when the motor isoperated, a blast of air currents will be created and will be dischargedthrough the air inlet chamber 13 and out of the openingsl,

against the surface to be renovated, 'and into the chamber l12, causingthe'A surface against which the blast has been directed to becomecleaned, as the foreign particles will be diso of. 1- r1`he-air"currentsthus formed by the fan will cause a circulation through the fan chamberand will be discharged through the opening 17 intriga passage 20, fromWhere they. will be driven through the passage 20 tovbe dischargedintoaseparator 21.

AThe separator' ispreferably in the form of a tank Which holds aquantity of liquid 22,

such as water or the like for washing the which revolve about a shaft24:. The members 23 are arranged within the path of the moving aircurrents, which are discharged into the separator 21 through the opening24 to strike the membersv 23 and rotate them, causing them to besuccessively moved through"v the liquid 22. This operation not onlyfilters or sifts the dust from the incoming` air, but causes the foreignparticles of dirt to be-deposited the receptacle, Vwhich latter isprovided with a clean-out plug o.

air, and mounted within the separator tanlr j 21 are a series ofretlculated members 23 Leading from the separator through the:

outlet opening 26, is a pipe 27 which` has communication with the inlet16 of the chamber 13 of the nozzle 10, so that the air currents passingout of the se arator 21 under pressure, will be forced t rough the pipe27 into the chamber 13'of the nozzle and Yout lof the outlet opening 15,as a blast, di-

machine and a handle( 29 isalso provided which is pivotally connected asat 30 with the machine2 so that the machine can be readily manlpulatedand the openings 15 may be moved over the surface to be renovated.

In the form of the invention shown in Fig. 5, the cleaning head 32 isadapted to be placed in contact with the surface to be renovated and thefan 33 which is operated by the'motor 34 operates in a chamber 35 whichhas communication with the head. Leading from the chamber 35 is a tubeor passage 36 which has communication with the bag 37, of any desiredsize and'configuration and constructed of any suitable material. Thisbag forms a receptacle for the dirt and foreign particles removed fromthe3 vsurface 'and is provided with an open end having a securing means38 applied to such end to hold the same closed.

The bag isdetachably connected with the tube or passage 36 so as to bereadily removed therefrom and a flexible member 39 maybe provided forsupporting the other end of the receptacle as is usual in devices ofthis character, from the handle 40.

Arranged within the ba orreceptacle 37 is -a partition 40 which orms afilter or screen and is constructed of any suitable material which willpermit the air currents to pass therethrough and remove the dirt andforeign particlesfrom the dust laden air., The partition divides the bagor receptacle into two compartments 42, 43, the former ref. provided forsupporting the weight of the late the machine.

surface to be renovated and these air curu rents are picked up by thefanv33 and again forced through the air circulation 'L -passage so thatthe same air currents ca* 4j? ev used over and over agam.

With this improved construction it will be manifest that the blasts ofair currents are directed Aback to the same portion of the surface te berenovated,thereby thoroughly I will be lifted from the fioor, -andwhich` weight 'is-ordinarily caused in other machines by the vacuum orsuction created in the cleaning head, which weight results in'increasing the effort necessary` to manipuf With the presentconstruction and by relieving the weight by the air lift, the wear onthe fabric over which the machine passes will be greatly reduced.

It will .also be manifest that the air which is directed through theopenings'l is clarifled, and the-same air current may be used over andover again, and the impure air will not be discharged into the room asis the case with other machines.. Obviously the separator 21 may beprovided with a re-v movable closure 31v if desired.

The lopenings 15 are preferably in the form of independent openingsarranged so as to extend transverselyof .the nozzle 10,

ceiving the deposit of dirt and the latter forming an exit chamber forthe lclarified air. Removably connected with the bag or receptacle andhaving connection with the chamber 43 is another tube or pipe 44, whichalso has' communication as at 45 with the nozzle 32.

The operation of this form of the invention is the same as that shown inFig. 1, that is to say, an lair blast is created by the fan 33 whichdischarges the air from the chamber 35 throu h the passage 36 into thereceptacle 42. Ihe a1r being filtered passes through the partition 41into the chamber 43, from there through thepipe 44back to the head 32 tobe discharged against the and the may-be arranged atl any desired anglewlth respect` to the surface to be renovated, to produce the bestresults.

While the preferredforms of the inven- I' tion have been herein shownand described, it is to be understood, ,that many changes may be made inthe details of construction and in the combination and arrangement ofthe several parts, without`departing from the spirit of this invention,and therefore it is desired that the drawings herewith submitted are tobe considered as being merely' diagrammatic.

Obviously the apparatusmay be of any desired size and conguration andconstructed of any suitable material.
